Millimeter Wave Spectroscopy of Rotational Transitions in Excited Vibrational States of Water.

Abstract

Several topics in millimeter wave spectroscopy were investigated under this program. A search has been conducted at 26.5 GHz and 67.7 GHz for rotational transitions in excited vibrational states of water with no absorption lines observed thus far. Calculation of the hyperfine structure of the J = O to 1 rotational transition of 6Li19F has been performed to account for the partial resolution of the transition in electric resonance zero field experiments at 89.7 GHz. Stark measurements on hydrogen sulfide and deuterated water (D2O) rotational transitions are reported, and dipole moment calculations have been performed. The quadrupole hyperfine structure of H2(33)S has been calculated from transitions in the millimeter wavelength region. Determination of the components of the magnetic g-tensor has been made from Zeeman effect measurements. In order to compare microwave linewidth measurements with infrared linewidth determinations, pressure broadening measurements on rotational transitions of SO2 are being performed. Preliminary data on the self-broadening of the 6(1,3) to 5(2,4) transition at 23 GHz are presented. (Author)
